在产生电磁感应透明的实验中，强耦合激光器的径向强度分布可以产生显著的空间折射率分布，当弱探测激光器调谐通过透明窗口时，弱探测激光器经历该空间折射率分布。这可能导致聚焦和散焦在分开的，但接近，探测激光失谐。在铷蒸气中使用连续波激光观察到这种行为，与我们的预测一致。
Within an experiment to produce electromagnetically induced transparency the radial intensity profile of the strong coupling laser can generate a significant spatial refractive index profile which is experienced by the weak probe laser as it tunes through the transparency window. This can lead to focusing and defocusing at separate, but close, probe laser detunings. This behavior is observed using continuous-wave lasers in rubidium vapor, in agreement with our predictions.
